Mr Kaplan said Dr Klein got involved because he was concerned about the children, Prince Michael, Paris Michael and Prince Michael II, having a normal upbringing not related to show business.

Jackson told Dr Klein repeatedly that he wanted his children to have a formal education and not be subjected to the rigours of travelling and performing, Mr Kaplan said.

Mr Kaplan surprised many by saying Dr Klein wanted a role in the children’s lives during a court hearing earlier this month.

A judge ruled that Dr Klein didn’t have legal standing to intervene, but told the doctor he could file a motion later if he still had concerns.

Jackson’s mother, Katherine Jackson, was granted permanent guardianship of the children during the hearing as spelled out in the singer’s 2002 will.

Dr Klein’s involvement in the case raised questions about whether the doctor could be the father of Jackson’s two oldest children, a rumour fuelled by tabloid reports and Dr Klein’s own cryptic answers when questioned on the matter.

Mr Kaplan said Dr Klein legally isn’t the father and that questions about whether he is the children’s biological father aren’t important.
